#for this example use test-mysql.sql from folder ../sql/

/* By default database type is MySQL: 'mysql'
* To change database type add database type argument shortly : for PostgreSQL 'pgsql', for Microsoft SQL 'mssql', for MySQL 'mysql'
* For example Microsoft SQL Server:
* $dbUtils=new DbUtils('mssql');
*/

$dbUtils=new DbUtils();

/* If not set global parameters is possible set custom parameters
/* $dbUtils->setParams(array('dbhost'=>'localhost','dbuser'=>'username','dbpass'=>'password','dbname'=>'database'));

$fetchMode=PDO::FETCH_ASSOC;


// Retrieve one row from table users
$row=$dbUtils->fetchRow("select * from users where id=1");
echo

// Retrieve multiple rows from table users
$rows=$dbUtils->fetchRows("select * from users");
for(
$i=0; $i<count($rows); $i++){

// Insert into table users

// Update table users
$sqlStr="update users set lname='corn' where id=1";

### Advanced Usage:

// Retrieve one row from table users
$bindValue=array('name'=>'id', 'value'=>1, 'dataType'=>PDO::PARAM_INT);
$sqlStr="select id, lname, fname, email from users where id=:id";
$row=$dbUtils->fetchRow($sqlStr, $bindValue, $fetchMode);
echo
'ID:'.$row['id'].' | Name: '.$row['lname'].' '.$row['fname'].(!is_null($row['email'])?' | Email: '.$row['email']:'')."\n";


// Retrieve multiple rows from table users
$sqlStr="select * from users where lname like :lname_like and fname like :fname and lname not like :lname_not_like";
$bindValues=array(
               
'fields'=>array(
                        array(
'name'=>'lname_like','value'=>'cor','dataType'=>PDO::PARAM_STR, 'like'=>LIKE_LEFT),
                        array(
'name'=>'lname_not_like','value'=>'cor','dataType'=>PDO::PARAM_STR, 'notLike'=>NOT_LIKE_RIGHT),
                        array(
'name'=>'fname','value'=>'mc','dataType'=>PDO::PARAM_STR)
                    )
                );
$rows=$dbUtils->fetchRows($sqlStr, $bindValues, $fetchMode);
for(
$i=0; $i<count($rows); $i++){
    echo
'ID:'.$rows[$i]['id'].' | Name: '.$rows[$i]['lname'].' '.$rows[$i]['fname'].(!is_null($rows[$i]['email'])?' | Email: '.$rows[$i]['email']:'')."\n";
}

// Insert into table users
$sqlStr="insert into users (lname, fname, email) values (:lname, :fname, :email)";
$bindValues=array(
               
'fields'=>array(
                        array(
'name'=>'lname','value'=>'corn2','dataType'=>PDO::PARAM_STR),
                        array(

                        array(
'name'=>'email','value'=>'corn2@mc.mail.hi','dataType'=>PDO::PARAM_STR)
                    )
                );
$dbUtils->insert($sqlStr, $bindValues);

// Update table users
$sqlStr="update users set lname=:lname where id=:id";
$bindValues=array(
               
'fields'=>array(
                        array(
'name'=>'id','value'=>1,'dataType'=>PDO::PARAM_INT),
                        array(

                    )
                );

* Format date
*/

$params=array(
   
'dateFrom'=>'dd-mm-yyyy',
   
'dateTo'=>'yyyy/mm/dd'
);

$date='22-07-2016';

echo

/**
* Check empty value (Unlike standart empty function isEmpty also assigns true if value contains whitespaces, newlines, tabs):
*/

$value=" ";

isEmpty($value); /* Returns true */

var_dump(isEmpty($value));
